Measuring transducers
G 400 for phase angle
PF 400 for cos ϕ proportional
PF400-FA
The G 400 measures the angle between sine wave formed current
and voltage.
The output signal is proportional to the angle in degrees.
There are two models, one for single-phase and one for 3-phase
systems.
The PF 400 for cos ϕ measures the angle between sine wave
formed current and voltage. The output signal is proportional to cos
phi. There are two models, one for single-phase and one for threephase systems.
The transducers in plastic cases are mounted directly on profiled
bar 35 EN 500022. Connection to selfopening clamps for 6 mm2
wires.
Transducers for mounting in 19" racks can be delivered in different
application types (see special leaflet). The rack modules are 8 TE
wide and in a 19" rack is place for 10 modules.
The transducers are manufactured according to IEC 688.

Design
GPF400BB
The two input quantities voltage and current are transformed in the
input transformer to a level adapted to the internal electronics and
give at the same time galvanic separation.
The noise on the input signals is filtered away in the phase true
lowpass filter.
In the following zero cross detector (Schmitt trigger) is the input sine
wave converted to a square wave.
The micro processor calculates the exact time difference T1
between the two input signals. Out of the relation T1/T is either the
phase angle (G) or the cosine (PF) between voltage and current
calculated.
The AC power supply comes from a transformer that gives a
galvanic separation. Those parts that need separate power get it via
a rectifying stage. The DC power comes from a switched unit that
gives galvanic separation and covers the span from 24 to 130 VDC.
